Hi guys I'm in the UK and I'm after some help with parts for my 1300 Turbo build..I've got a small turbo,a little garret T5..and wanted to know how much boost stock block would hold..?they sell some dished barrels and Pistons but they are cast,how much boost do you guys think they would hold..not looking for massive power just want to build a 1300 turbo to know I've done,satisfaction more than anything..been thinking about it for a while now.would stock valvetrain,heads and cam work okay?like I say not going to be pushing loads of psi really just want something different that works..
Cheers
Jonny

Re: 1300 turbo build
FWIW I used to run a conventionally-aspirated (2x35PDSI Solex) 1300 at 12.7:1 circle-tracking - full-load most of the time (although events seldom lasted more than 10-15 minutes), never had any piston problems with stock KS flattops. Only issue I had was finding pump gas with enough octane for it (class rules didn't allow racing fuel). At 100% volumetric efficiency the cylinder pressures would be comparable to the stock 6.6:1 with nearly an atmosphere of boost...in the real world, perhaps about the same as you'd have at 10 psi or so. Based upon that, I'd think that any boost level which didn't cause detonation with Premium petrol should be safe indefinitely.
I'd want to run new 1600 valvesprings, shimmed up .030", minimum - or some inexpensive HD singles. Stock pushrods should be all you need with either choice.
Kept under ~4500 RPM the stock rockerarms should stay together, but I'd go ahead and set it up with "solid" shafts and lose the clips & washers...if you don't they'll probably fail you eventually.

Re: 1300 turbo build
Is that an actual 1300 cc's you are going to be running or just a 1300 bug.???
If a 1600 engine and you will be happy with no more than 10-13 lbs boost then a turbo with compressor and turbine wheels at or under 1.5 inches inlet diameter will be fine.
Any larger and you will have lag unless you rev it over 5500 rpm.
Ignition control is the key and of course fuel delivery helps too.
Keep your iat's down to keep the engine happy.

Re: 1300 turbo build
Was trying to keep it 1300cc in size..just because haven't seen many done here

Re: 1300 turbo build
Like I said above.....Measure your Compressor inlet diameter and make sure it is around 1.5" or less and you might be able to get some boost with 1300 cc's.Jonny-thevolkscave wrote:Was trying to keep it 1300cc in size..just because haven't seen many done here
You will definitely need a small turbo.
Something like the Dodge Stealth turbo from the TT but only one of them.
The Dodge turbo is on the right. It is a tiny thing.
The turbo on the left is the Subaru WRX turbo that I run on my 1679 cc engine. As you can see the wheels are close to the same size but the housing is much smaller.
A KKK K03 might be small enough too.
I have never heard of a T-5 turbo before but if it is in the T-3/T4 family it will be too big for you.
Measuring the Inlet diameter or outlet diameter will give you a good idea of how big it is.
Post some pics of it.

Re: 1300 turbo build
A wreckers would be a good place to start. Maybe something off a turbo diesel. They run much smaller turbos than petrol motors. I'm running the smaller turbo off a twin turbo liberty. You'll need something smaller.
